Capsular Contracture After PMRT Using Prepectoral Versus Subpectoral

Status Not yet recruiting

Clinical Trial Summary

The purpose of this study is to prospectively compare and analyze the incidence of complications in patients undergoing postmastectomy radiation therapy after breast reconstruction with subpectoral and prepectoral placement of implant. Investigators hypothesized that immediate acellular dermal matrix-assisted implant-based breast reconstruction with prepectoral implant placement would result in lower risk of capsular contracture after postmastectomy radiation therapy(PMRT) compared with acellular dermal matrix(ADM)-assisted implant-based breast reconstruction with subpectoral implant placement.

Clinical Trial Description

OUTLINE: This is a single center randomized clinical trial. Participant recruitment and enrollment will occur at Gangnam Severance Hospital Breast Cancer Center for 4 years, followed by one year of follow up data collection and analysis.

Arm I (Prepectoral): immediate ADM-assisted implant-based breast reconstruction with prepectoral implant placement.

Arm II (Subpectoral): immediate ADM-assisted implant-based breast reconstruction with subpectoral implant placement.

This clinical study is aimed at patients who have been diagnosed with breast cancer and who have undergone a total mastectomy for the therapeutic indication, and who are planning to undergo implant based reconstruction and postmastectomy radiotherapy.

It will be carried out prospectively in a single institution, and the study will be divided into two groups, subpectoral implant and prepectoral implant, according to the reconstruction method.

A total of 96 patients or 48 patients per arm will be recruited. Randomization will be accomplished using randomly permuted blocks, and randomization will be stratified on the basis of reconstruction method. (tissue expander insertion or direct-to-implant)

After completion of study treatment, patients are followed for 1 year for observation of capsular contracture and patient reported outcomes. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
